Description
Technical Field
[0001] The utility model relates to the technical field of pipeline air pressure monitoring devices, in particular to a pipeline air pressure monitoring device. Background Art
[0002] A natural gas pipeline is a pipeline that transports natural gas from a production site or processing plant to a city's gas distribution center or industrial enterprise user. Using natural gas pipelines to transport natural gas is a method of transporting large quantities of natural gas on land. Natural gas pipelines require regular testing of the natural gas pressure at intervals to determine if there are any leaks. Patent CN205859619 proposes a sensor-based natural gas pipeline leak alarm device that uses an external fiber optic temperature sensor to monitor the gas in the pipeline, thereby ensuring the safe transportation of natural gas. Since natural gas pipelines are mostly used outdoors, the use of sensors requires protective components to improve their monitoring accuracy and extend the sensor's service life. In view of the foregoing, this application proposes a pipeline pressure monitoring device with protective functions for monitoring pipeline gas sensors. Summary of the Invention
